Abstract (en)

The present disclosure relates to novel methods and apparatuses for generating hydrogen sulfide or hydrogen selenide gas from decomposition of a solid precursor. In some embodiments, the generated gas is cooled so as to condense a by-product of the decomposition and thereby increasing the purity of the gas. In some embodiments, the generated hydrogen sulfide or hydrogen selenide gas is used to prepare metal sulfide or metal selenide films.
